In this guide, we will walk you through the step-by-step process of how to disassemble this shotgun while providing troubleshooting tips and other useful information.

Tools Needed to Disassemble Your JC Higgins Model 20

Before beginning the disassembly process, ensure you have the following tools ready:

• Gun cleaning kit – for cleaning the internal components once disassembled.
• Flathead screwdriver – to remove screws and certain parts.
• Penetrating oil – useful for loosening stuck or rusted parts.
• Cloth or rags – for wiping off grease and oil.
• Parts tray – to organize screws and small components as you work.
• Protective gloves – to ensure your hands are safe from sharp edges or oils.

Step-by-Step Guide to Disassembling the JC Higgins Model 20 Shotgun

Step 1: Ensure the Shotgun is Unloaded

Before you start disassembling any firearm, safety should always be your first priority. Always ensure that the shotgun is unloaded. Double-check the chamber and magazine to make sure no shells are present. A simple safety check will save you from any accidental discharge.

Step 2: Remove the Barrel from the Receiver

The first major component you’ll want to separate is the barrel. To do so, hold the shotgun with the muzzle pointing down. With your fingers on the receiver, pull the barrel locking mechanism back to release the barrel. You may need to use a flathead screwdriver if the mechanism is too tight. Once the locking mechanism is disengaged, carefully pull the barrel away from the receiver.

Step 3: Separate the Forearm from the Action

The forearm is the part of the shotgun that covers the magazine tube and connects the barrel to the receiver. To remove the forearm, press the release button or latch located on the action. Then, gently slide the forearm off of the magazine tube. If it’s stuck, you can apply a small amount of penetrating oil and wait a few minutes for it to loosen.

Step 4: Remove the Trigger Group

The trigger group houses several small internal components such as the trigger, hammer, and sear. It’s important to disassemble this section carefully to avoid losing any small springs or parts. To remove the trigger group, look for the retaining pins that hold it in place. These are usually located on the sides of the receiver. Using a small punch tool or a flathead screwdriver, push out the pins, and the trigger group should slide free.

Step 5: Remove the Action Bars and Bolt

Once the trigger group is removed, it’s time to take out the action bars and bolt. Start by pulling the action bars rearward until they are completely out of the receiver. Once the action bars are removed, carefully slide the bolt out of the receiver. This may require a little wiggling to free up any parts that might be jammed or stuck due to dirt or grime. Cleaning this area thoroughly will ensure smooth operation when reassembled.

Step 6: Clean the Components

Now that the shotgun is disassembled, it’s the perfect time to clean each part. Using a cleaning kit, wipe down the barrel, receiver, forearm, action bars, and all internal components. Be sure to use a good solvent to remove any buildup of carbon, dirt, and debris that may have accumulated over time. Also, inspect the parts for any signs of wear or damage that might require replacement.

Troubleshooting Tips for Disassembling Your JC Higgins Model 20 Shotgun

Difficulty Removing the Barrel

If you find it hard to separate the barrel from the receiver, the locking mechanism might be stuck. Try applying a small amount of penetrating oil around the mechanism and wait for a few minutes. After this, attempt to disengage the mechanism again. If it still doesn’t work, gently tap the mechanism with a soft mallet to loosen it.

Stuck Forearm

Sometimes the forearm can become stuck due to dirt or oil buildup around the magazine tube. In this case, a few drops of penetrating oil can help loosen the forearm. If this doesn’t work, inspect the latch or release mechanism for any signs of damage or obstruction. Clean the parts and retry removing the forearm.

Loose or Worn Trigger Group Pins

If you notice that the pins holding the trigger group are loose or worn, it’s best to replace them. These pins are critical to the proper function of the trigger, so any damage could cause malfunction. You can find replacement pins at most gun parts retailers or contact the manufacturer directly for recommendations.

Reassembling Your JC Higgins Model 20 Shotgun

Reassembling your JC Higgins Model 20 is essentially the reverse of disassembly. Start by carefully inserting the bolt and action bars back into the receiver. Afterward, reinstall the trigger group by aligning it with the pin holes and securing it in place with the retaining pins. The forearm and barrel should be reattached as well, ensuring that all components lock into place properly.

Once the shotgun is fully reassembled, perform a few function checks. Dry fire the shotgun (without any ammunition) to ensure the hammer and trigger operate smoothly. Check for any rattling parts or misalignment before fully loading and using the firearm again.

Conclusion

Disassembling a JC Higgins Model 20 Shotgun may seem like a complicated process at first, but with patience and the right tools, it becomes a manageable task. Regular disassembly and cleaning not only improve the performance of your shotgun but also extend its lifespan. Always ensure that you follow the safety protocols and take your time when handling each component. If you’re unsure about any step or encounter difficulties, don’t hesitate to consult an expert or visit a professional gunsmith.

Remember, keeping your JC Higgins Model 20 in top working condition requires care and attention to detail.
